C++ :: Generate Random Numbers Within Specific Range?

C :: Calculate Black Body Spectra Over User-entered Range Of Wavelength And Temperatures
Jul 29, 2013I tried to write a code to calculate black body spectra over an user-entered range of wavelength and temperatures. The equation I'm trying to code is the second one this image (stolen from Wikipedia)The syntax to run it is bbgrid lambda_inic lambda_final temp_inic temp_final inc_T inc_lambda
where bbgrid is the name of the program, lambda_inic and lambda_final are the limits of the wavelenght range (in units of angstroms, 1A=10⁻⁰m), temp_inic and temp_final are the limits of the temperature range (in Kelvins) and inc_T and inc_lambda are the increments. What I want to do is, given the ranges of temperatures and wavelengths, to run the code over the lambdas and the temperatures.
The problem is that the behaviour of the intensities (what I'm calculating) is erratic. Sometimes it is highly positive, sometimes immensely negative and turning between those two. As an example of an output file, I'm getting things like this:
3100 1915076038
3110 -1233496775
3120 1741010116
3130 1229780625
3140 421722788
3150 -1874760945
3160 1654746252
3170 1062468321
3180 -795217626
3190 -1141129750
3200 -1570716956
3210 539385985
While I was trying to debug the code, I found the problem may reside in the exponential factor in the denominator. I wrote some lines to calculate and print on the screen only the exponential, and it was oscillating like crazy. The output file should produce curves like this:
Code:
#include<stdlib.h>
#include<stdio.h>
#include<math.h>
#include<string.h>

C :: Calculate Prime Numbers In Range And Return Count Of Prime Numbers

C++ :: Program That Prints Prime Factors Needs To Have Them Output In A Specific Way
Jan 6, 2015I am working on an assignment to enter a number and print all the prime factors of that number. I have that working, but the assignment demands the output be formatted in a strange way which I can't figure out. For example, in my current program entering 10 gets me 25, which is actually 2 and 5. But it should get me: ( 2 * 5 ) but I can't figure out how to do this. On the chance you need it, my code is below:
Code:

int main( )
